Two more victims, who sustained burn injuries in a gas cylinder blast at Kaliakair in Gazipur on March 13, died while undergoing treatment at Sheikh Hasina National Institute of Burn and Plastic Surgery, taking the death toll to 16.

The resident surgeon of the burn institute, Tariqul Islam, said that 24-year-old Lalon, who suffered 40 per cent burns, breathed his last at about  3:20am on Sunday while 22-year-old Nadem, who suffered 55 per cent burns, died on Saturday night.

Five, out of the ten victims undergoing treatment at the institute, were in a critical condition, he added.

Six victims were discharged from the hospital.

At least 35 people were injured as a cooking gas cylinder exploded at a workers colony next to Top Star Garment Factory in the Telir Chala area on March 13.

Gazipur fire service deputy director Abdullah Al Arifin told New Age that the knob of a gas cylinder got opened while it was being connected to a stove in a house, causing the gas leak.

The owner of the house immediately threw the cylinder at the road, where some people were cooking on a wood-fired stove.As the fire from the wood-fired stove came in contact with the leaked gas from the cylinder, it caused the explosion and a huge flame.
